    General solution

    Not sure how to go about this....

    Find the
    general solution to the equation:

    x+2y(x^2+1) dy/dx = 0.

    Could anyone explain? Thanks.

    That's a separable differential equation. Write it as (in other words, separate it!) 2ydy= -x\sqrt{x^2+ 1}dx and integrate both sides. To do the x integration, let u= x^2+ 1.
